A horror story is told to deliberately scare or frighten the audience, through suspense, violence or shock. H. P. Lovecraft distinguishes two primary varieties in the "Introduction" to Supernatural Horror in Literature: Physical Fear or the "mundanely gruesome" and the true Supernatural Horror story or the "Weird Tale." The supernatural variety is occasionally called "Dark Fantasy," since the laws of nature must be violated in some way, thus qualifying the story as "fantastic."
